Product Details

The COMP Cams Mutha' Thumpr K34-601-9 is a complete hydraulic roller camshaft kit engineered for Ford 429 and 460 cubic inch V8 engines. This aggressive camshaft delivers the signature Thumpr loping idle and hard-hitting performance that muscle car enthusiasts demand, with 235/249 degrees of advertised duration for excellent throttle response and powerful acceleration.

Complete K-Kit Includes Everything You Need:

  • Hydraulic roller camshaft with 235/249 advertised duration
  • Hydraulic roller lifters designed for Ford 429/460 applications
  • High-performance valve springs for increased RPM capability
  • Precision-machined retainers and valve locks
  • Valve stem seals for proper oil control
  • Timing chain set for accurate cam timing
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

This all-in-one kit eliminates the guesswork of component matching and ensures all valvetrain components are properly engineered to work together. The Mutha' Thumpr profile is ideal for street performance builds, muscle trucks, and classic restorations where aggressive sound and strong mid-range power are priorities. The hydraulic roller design provides maintenance-free operation while delivering performance that rivals flat tappet racing cams.
